High-performance ultra-wideband radiation unit applied to 5G system

The utility model discloses a high-performance ultra-wideband radiation unit applied to a 5G system. Including a PCB substrate, the lower end surface of the PCB substrate is provided with a radiationunit balancer. The upper end surface of the PCB substrate is a radiating surface; the radiating surface adopts a dual-polarized oscillator structure; the dual-polarized oscillator structure comprisesfour radiation arms which are orthogonally arranged, in the four radiation arms, connecting grooves are formed in the portions, close to the edge of the PCB substrate, of every two adjacent radiationarms, and the portions of the connecting grooves are connected through metal copper foil on the surface of the PCB substrate, so that every two adjacent radiation arms are connected together. Each polarization of the radiation unit designed by the scheme is formed by connecting two deformed folded oscillators in parallel, and a multiplexing technology is skillfully adopted, i.e., the polarized folded oscillator multiplexes
